T-Hydro TBHP provides a readily available and convenient source of active oxygen suitable for diverse oxidation technologies. Lyondell`s epoxidation of propylene to propylene oxide accounts for the largest commercial application for TBHP. Producers of initiators use T-Hydro solution to synthesize many perester, dialkyl peroxide and perketal derivatives.The product itself serves as a free radical initiator for polymerizations, copolymerizations, graft polymerizations and curing of polymers. T-Hydro TBHP offers advantages of versatility, regioselectivity, stereoselectivity, chemoselectivity and reactivity control with catalyst choice, mild reaction conditions and bulk availability. T-Hydro TBHP finds use in preparing specialty chemicals required by fine chemical and performance chemical industries such as pharmaceuticals and agrochemicals. TBHP can selectively oxidize hydrocarbons, olefins and alcohols. Asymmetric epoxidation and kinetic resolution with TBHP can provide access to complex chiral intermediates.

Physical Hazards

T-Hydro TBHP is a highly reactive product. The three types of significant physical hazards are flammability, thermal and decomposition due to contamination (see Section 2 for toxicity hazards). To minimize these hazards, avoid exposure to heat, fire or any condition that will concentrate the liquid material. Store away from heat, sparks, open flames, foreign contaminants, combustibles and reducing agents. Inspect containers frequently to identify bulges or leaks.

Flammability Hazards

T-Hydro TBHP is highly combustible with a flash point of 38°C (100°F).Once ignited, the material burns with a flare-burning effect. During combustion, thermal decomposition may occur as well. As a peroxide, T-Hydro TBHP vapors can burn in the absence of oxygen.Determination of flammability limits are affected by temperature, pressure, the volume of sample tested and type of ignition source. The lower flammability limit of T-Hydro solution vapors in air is 5.75 vol% TBHP at 80°C (176°F). The upper flammability limit is 100 vol% TBHP.Because TBHP is capable of decomposing at elevated temperatures with the generation of oxygen, the flammability limits in nitrogen were also measured under the above conditions. The lower flammability limit in pure nitrogen is 42.8 mol% and the upper limit is 100%. The lower flammability limit will decrease as decomposition occurs and oxygen is generated, depending on temperature and time. Similarly, the flash point of T-Hydro TBHP in pure nitrogen is 74°C (165°F) and will decrease as decomposition occurs.

Thermal Hazards

Compared with most other hydroperoxides, T-Hydro TBHP has high thermal stability. The material is stable at temperatures below approximately 38°C (100°F), and unadulterated material may keep for several months without a significant loss of activity. However, at increased temperatures T-Hydro solution will deflagrate1 rather than detonate with a concurrent generation of oxygen, highly flammable isobutylene and incomplete combustion products such as carbon monoxide. The thermal decomposition rate and half-life of TBHP will change dramatically depending upon specific conditions. Surface-tovolume effects as well as container material and trace contamination may change rate and temperature relationships for decomposition.
